With left-handed-hitting Eric Thames called on to pinch-hit, the right-handed-hitting Cain behind him and left-handed-hitting Christian Yelich after that, Maddon toggled the relievers between left field and the mound until all three were retired in order.

‘‘I’ve talked to them about doing it before, and it just popped,’’ said Maddon, who eventually had Willson Contreras in left for Yelich, who actually sliced a ball there near the foul line for the final out.

‘‘It was a little terrifying, to be honest,’’ said Duensing, who borrowed left-hander Justin Wilson’s larger glove because the Cubs’ only left-handed outfielder (Heyward) was using his. ‘‘But it was fun. Not that it was ever a box, but I can check it off.’’

It was the first career outfield appearances for both pitchers.

Darvish, Edwards updates

The Cubs hadn’t set the schedule yet, but right-hander Yu Darvish fared well enough overnight after throwing a bullpen session Tuesday that he’ll throw a second one during the series in St. Louis, Maddon said.

Darvish, who has been on the disabled list the last three weeks because of triceps soreness, said after his 28-pitch session that he hopes to return to the rotation before the All-Star break.

Reliever Carl Edwards Jr. (shoulder soreness) also fared well after throwing Tuesday and likely will throw Friday in St. Louis.

The Cubs won’t set a timeline for the return of either pitcher, but Edwards is considered much closer than Darvish.

This and that

When Kyle Schwarber beat the right-side shift with a single up the middle in the fourth, he snapped an 0-for-17 skid.

• The Cubs’ rotation has a 2.46 ERA in the team’s last 16 games.

• Javy Baez tied his 2016 career high with his 12th stolen base in the second. It was his fourth steal of third this season. He also has a steal of home.
